Abstract
A device and a method for producing zones of desired air permeability in the enveloping material of rod-shaped articles, particularly in the tobacco-processing industry. The device includes a beam-guiding device for focusing an energy-rich beam, generated by a radiation source, onto the enveloping material in order to form perforation zones, as well as a multiple beam-generating device that generates a multiple beam from the single beam. The multiple beam-generating device is provided with at least one optical element that is fixed in its operating position relative to the beam.
